i started learning english since primary school,.i have memorized a lot of vocabularies nd slangs.this gives me a big advantage,i can understand most of the article or english newspaper.however,my grammar was very poor,i used to be confused about when to use present perfect tense,when to use present simple tense or something like that.besides,i am afraid of writting composition.i will always fail bacause of my grammar mistake.
anyway,i am working very hard now,i believe that my english will improve faster.希望能对你有所帮助.嘎嘎.KK..
